gum rosin can be used as a glazing agent in medicines and chewing gum. It is denoted by e number e915. A related glycerol ester (e445)can be used as an emulsifier in soft drinks. In pharmaceuticals, rosin forms an ingredient in several plasters and ointments.
in industry, gum rosin is a flux used in soldering. The lead-tin solder commonly used in electronics has about 1% rosin as a flux core helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer formed at the surface back to metal. Gum rosin is frequently seen as the burnt or clear residue around new soldering.
